Not sure I entirely understand the question. MSConvert will work the same with Astral data as with other instrument platform data. From the GUI, the attached settings work.

From the command line you can use ... "C:[use your path]\msconvert.exe" --zlib --simAsSpectra --filter "peakPicking vendor msLevel=1-" --filter "titleMaker <RunId>.<ScanNumber>.<ScanNumber>.<ChargeState> File:"""^<SourcePath^>""", NativeID:"""^<Id^>"""" "C:\Users\macco\Downloads\20230403_OLEP08_EV_1ug_MB_30min_AS_10ms_4Th_1.raw"

I hope this helps,
Mike
